VALVED HOSE NOZZLE.

Application ined March 2s, 1923. serial No. 628,336.

provide a simple, compact, durable nozzle,`

readily operated to control with precision the fiow of liquid and maintaining itself tight without attention under all conditions of use. A A

Further aims and advantages of the inconnection with the deillustrative embodiment accompanying drawings,

vention appear in shown in the wherein- Fig. 1 is a side view of a valved nozzle for hose pipes; fFig. Q is a longitudinal section of the same on the line 2-2 -in Fig. 1

Fig. 3 is a side view of the movable valve member removed from the nozzle; and

Fig. 4l is an end view of the valve member shown in Fig. 3.

The form of theV invention illustrated in' the drawings is intended particularly for fire' depart-ment and similar service where strength and reliability of operation are essential to satisfactory performance, and

quick and certain control is highlydesirable 5' but the invention is equallyf'applicableto commercial, household and othery less exact ing service.

Referring to Figs. 1 and v2, the shut-V olf device therein shown comprises a body 10 which, in the form shown, is made in two parts, the valve containing nipple 11 being removable for convenience in manufacture and to facilitate repair. The body has suitable means, such as a screw threaded flange 12, at one end for connecting it to a hose or other pipe 13, and a vnozzle 14 at the opposite end. The nozzle 14 is adjustably secured to the nipple portion of the body by any suitable means, such as a screw joint 15, and is prevented from unscrewing to the point of separation from the body by means of a set screw 16, engaging in a groove 17 cut aroundv the body. The nozzle vis mounted for rotation in a frame 18 provided with handles or grips 19, and may be rotated by any convenient means, such as the radially projecting knobbed spokes 20, readily grasped by the hand, or by the fingers or thumb while the hand grips thel handle to hold the device. rPhe nozzle may; be provided with a removable tip 21. of the 'charge end of the valve desired size of. orifice for' directing the stream. ln the form vshown in the drawings, the orifice is the saine size as'the disA charge opening from the valve. l

.The nipple 11 has a flat seat 22' formed on a. shoulder'concentric with the discharge passage. Thisseat faces the end of the valve body through which the liquid enters (seel Fig. 2) and is adapted to cooperate with an axially slidable valve 23 arranged in the discharge 'passage to close the passage .when the valve is seated thereon. *The valve is tubular for the greater part of its length, one end (that near the seat 22) being closed and the other end (which projects Outrof the discharge end of the discharge passage) being open. The closed end of the valve 23 has an axial stud carrying a circumferentially projecting cup or ,flange 24 for supporting Vthe packing 25 against* the vvalve seat 22 when 'he valve is closed. A nut 261 'i or other suitable retaining means enables the flange and packing to be removed, if neces-v sary, for cleaning or renewal. The valve 23 is provided with suitably sl'i'apei'l. orifices 27` in its side wall near its closed end for adf mitting liquid into thefdischarge passage 'when the vvalve is unse-ated, and for aiding in controlling Ithe amount of flow, the latter depending on the amount of 'opening of the valvev and consequent uncovering of the orifice. An axially extending diaphragm or. vane 28 is arranged in the dispassage for preventing swishing and splashing of the water ror, other liquid emerging from the nozzle. y

The valve 23 may advantageously be held in place'in the discharge passage'in the body by means of a screw collar 29 on its open end and a compressible spring 30 surroundingv its open end between the collar and the nipple end of the body.L The spring is received in a-counterbore or enlargement 31 of the discharge passage andy its inner vend abuts against the shoulder in thebody at the inner end of this counterbore. This to hold the valve 23 against its seat, and when the valve is lforced off from its seat by screwing the nozzle'll. toward-the body (to the left in Figs. land 2) the spring is compressed'into the coun-A terbore 31.`

The operation of the ly simple, reference spring tends device is extrememerely rotating the nozzle with to the body' as' to screw it to l as is necessary to ward the valve moves the valve away from its seat to expose the ports 27 moie` or less permit the flow of the quantity ot water desired.Y Screwing the nozzle the opposite kway permits the valve to return lunder the influence of the pressure of liquid and the spring 30 until 'it seats, thereby cutting off the iow. The valve willy remain in any intermediate position to which'it may be moved by the rotation of the nozzle until the nozzle is further rotated..

' There are no metal to metal joints requiring attention to maintain tight, and which are liable to corrode and stick; and there is little, itany, danger of injuring the packing 25 because the valve cannot be forced shut` against its seat by the screwV nozzle.

lFurthermore, by removing the set screw 16 I and'. unscrewlng the nozzle from the body,

all parts are readily taken olf or out for inspection and cleaning. The packing 25 may readily be renewed when worn out, but if a good grade of steam packing be used this will be seldom. This packing is soft enough to maintain a tight fit against the seat, and tough enough to stand the pressure and wear of the water. As thereis no movement of the valve upon its seat there is no wear from this cause.

The form of valve andnozzlepermits the flow in a solid stream without splashing at all stages o1c opening.

The invention .is particularly Vadvantageous for pipe systems where it is desirable to open and close the shut-oft' valve without causing shock from rapid changes in pressure or velocity in the pipe.

Having described an embodiment of my invention for purposes of illustration, without restricting myself thereto, I claim and combination, a tubular body member adapt ed for attachment to a hose and presenting Ya valveV seat near its inner end, a tubular valve slidably arranged in said body and adapted to said seat, a nozzle threaded on the outer end of said body having means'for engagingv said valve for moving it away 'from said seat, said body presenting a counter-bore at its outer end and said valve presenting a shoulder' beyond the end of said body, and a spiral spring surrounding said tubular valve arranged in said counter-bore and engaging said shoulder tor maintaining` said valve in operative engagement with sai-d nozzle, and to maintain said valve in assembled relation.

3. A valved hose nozzle comprising, in combination, a body portion, a tubular valve axially arranged in said' body portion, means 'for actuating said valve, and a transverse vane secured in slot-s in said tubular valve adjacent the discharge end adapted 'to prevent splashing or swisaing of the liquid discharging therefrom before. it enters the nozzle tip.

In testimony whereof, I have signed my name to this specification.
